After heading to the Laugh Factory comedy club together Thursday night, Justin Bieber and Selena Gomez were spotted back together again at Japanese restaurant Yamato in San Fernando Valley, Calif., Friday evening, a source told E! News.

According to the source, the former Wizards of Waverly Place star drove to the restaurant, and the Biebs showed up in his car a few minutes later.

"Something must have happened inside the restaurant, because 10 minutes after he arrived, they both stormed out looking stone-faced," the source said. "They were very serious and did not look happy at all. She got in her car, and Justin got into his.

"Selena drove off and Justin just sat there for a few minutes. I think he was waiting for her to calm down. He then drove to her house. When he got there, he started buzzing her gate. But she was obviously not letting him in. He continued trying. Then, after a while he got out of his car, he was obviously frustrated and went up to the gate and started yelling 'Selena' over it. But...she was not coming out."

"It was at this point [Justin] started to yell at the paps," the source continued. "He was obviously annoyed that they were there and witnessing everything. He was mad. Selena then came out, because there was such a commotion, he got in his car and left."

But, it appears that wasn't the end of the couple's tumultuous evening.

"Something must have happened overnight, though, because his car was there this morning."

The couple first called it quits two weeks back, before reuniting a few days later in Los Angeles.
